Imported tungsten lamp
Imported tungsten lamp, so that your instrument performance is more stable, test accuracy is more accurate and reliable.
Halogen lamp is an inflatable incandescent lamp filled with halogen group elements or halides. In common incandescent lamp, the high temperature of filament causes tungsten evaporation, and the evaporated tungsten deposits on the glass shell, resulting in the phenomenon of blackening of the glass shell of the lamp. In 1959, the halogen tungsten lamp was invented, and the phenomenon of blackening was eliminated by using the principle of halogen tungsten cycle.
Preparation
The recrystallized structure of tungsten wire can form a good swallow-tail lap structure with a ratio of length to width greater than 12. It has high strength at high temperature, good droop resistance at high temperature and deformation resistance at high temperature under high temperature ignition point.
